Question

read each question carefully and decide which is the best answer. fill in the bubble with the letter of the correct answer on your answer sheet. 1. which organic compound produced during photosynthesis is used by plants to store energy? a atp b dna c glucose d water 2. the chemical equation for photosynthesis is shown below. 6co₂ + 6h₂o → c₆h₁₂o₆ + 6o₂ which of the following statements about photosynthesis is true? a the reactants are carbon dioxide and glucose. the products are water and oxygen. b the reactants are carbon dioxide and water. the products are glucose and oxygen. c the reactants are glucose and oxygen. the products are carbon dioxide and water. d the reactants are glucose and water. the products are carbon dioxide and oxygen. 3. deforestation is the permanent destruction of forests in order to make the land available for other uses. this process leads to fewer plants being available to conduct photosynthesis. which of these is a possible effect of deforestation on the process of cellular respiration? a more water is available for use during cellular respiration. b less oxygen is available for use during cellular respiration. c more glucose is available for use during cellular respiration. d less carbon dioxide is available for use during cellular respiration.

Explanation:

1. During photosynthesis, glucose is the organic - compound produced and used by plants to store energy. ATP is an energy - carrier molecule but not the main energy - storage compound. DNA is the genetic material, and water is a reactant or product in many biological processes but not an energy - storage compound for plants from photosynthesis.
2. In the chemical equation of photosynthesis $6CO_2 + 6H_2O

ightarrow C_6H_{12}O_6+6O_2$, the reactants are carbon dioxide and water, and the products are glucose and oxygen.

1. Deforestation reduces the number of plants. Since plants produce oxygen during photosynthesis, less oxygen will be available for use during cellular respiration.

Answer:

1. C. glucose
2. B. The reactants are carbon dioxide and water. The products are glucose and oxygen.
3. B. Less oxygen is available for use during cellular respiration.
